      ▌ Global Warming, as Well as the Ever-increasing High Temperatures and Humidity Make
        Anti-humidity Equipment a Necessity.

     According to professional studies, moisture in the air will cause objects to mildew, change in quality,
     fade in color, become old, age, grow water stains, malfunction because of corroded parts, cease to
     function, have paper jam, change in flavor, change in pitch, lose the shine – the perfect environment
     in which fungi grow is: temperatures between 20 and 38℃, and humidity between 60 and 100% RH.
     Therefore, the damage and aging to most objects have mostly to do with humidity that results in      inconvenience such as the loss and maintenance of objects, the difficulty to maintain, dispose and
     repurchase – or visible, invisible loss of assets. Taking medicines or eating food that is
     degenerative has potential health risks, so it is imperative that the above should be avoided.


      This, in fact, includes:

      1. Industrial humidity hazards jeopardize production process

     the results of various surveys show that a main reason causing over 25% of defective industrial      products is the damage due to the nonexistence of low-humidity storage; this would include high-     tech photoelectric, electronic, biotech, food, pharmaceutical, optical industries, et al. Take, for      example, the electronic industry that has the widest applications, the stages of defective production      process include
     (a) damage due to micro-cracks in the heating process during SND/IC sealing and packaging;
     (b) the water hazard during SMT reflow soldering because of returned water temperature in the
           baking process;
     (c) mildew and humidity stains on LCD boards;
     (d) IC oxidation due to humidified sealing materials;
     (e) interlayer separation of PCB boards because of the humidity generated by temperature
           variations, et al.

      2. Storage of audio-visual data

      audio-visual storage media such as audio (or video) cassettes or discs, memory cards, classic      
     
CDs and DVDs, various academic, civil, business files, as well as compressed data, et al, can
      easily grow mildews that deteriorate or destroy important data and cause irrecoverable damage
      after extended desiccation of moisture.

      3. Photography-related work and collections

      desiccation and mildewing can happen to photographic equipment such as regular digital cameras,       professional cameras, binoculars, video cameras, and microscopes, as well as expensive and      
     
sophisticated equipment relating to optical measurements, eye exams and health exams, and
      items applied in automated manufacturing, et al. Once the lenses mildew, they are not able to return       to the original sharpness even though after repairs because mildews are often invisible to human       eyes. The damage and repurchase incurred in videotaping and photographic work will be difficult to       estimate.

      4. Paper products

      these include collections of vintage stamps and money bills, contracts and deeds, photo albums,
      important documents, books, paintings, printing paper (paper that desiccates moisture will cause
      printer jam and affect the quality of printing), et al. Paper that desiccates moisture easily attracts dust
      and becomes stained, as well as forms water marks, mildews that generates odor, et al, all of
      which affects the value of the collections.

      5. Sophisticated inspection equipment and materials

      these include digital equipment such as mobile phones, MDs, et al, and sophisticated equipment
      relating to R &D engineering, production process, military and police intelligence, education,
      medicine, inspection, network administration and audio-visual departments; also, photoelectric
      semiconductor components, powder materials, electronic parts, accessories, samples, reagents
      and metal materials, et al. They are expensive and difficult to obtain, so potential corrosion and
      metamorphosis due do humidity will ultimately impact on the progress and results of use,
      inspection and R & D.

      6. Household food and medicines

      it is easy for things such as tea, coffee, powdered milk, dried goods and food, Western and Oriental       medicines, health foods, raw materials for medicines or food to attract moisture and become
      hardened pieces, change in quality and color, mildew, change in flavor or even generate cancer-
      inducing ingredients that affect the health and taste of your family.

      ▌An Analysis of Different Anti-humidity Tools
 
Dehumidifier

  This is limitedly effective to dehumidification of space, but unable to reach 
  the desired humidity for object storage. Humidity will rapidly rise up once the
  machine ceases to operate causing secondary humidity hazard; what is 
  also involved is power consumption, the need for water disposal and the
  inability of continual dehumidification.

Air Conditioning

  This is often used in large-space dehumidification to solve the humidity
  hazard of objects, but is often turned off after work hours for energy
  conservation due to its massive consumption of electricity. Such an act,
  however, lets the objects in the space incur moisture condensation and
  counter-humidity resulting even more severe humidity hazard. As well, its
  dehumidification limit is between 60% and 50% RH that cannot completely
  solve the low-humidity storage problem of objects.

Refrigeration

  This approach has low-temperature dehydration function, but the incurred
  temperature variation as objects are taken out of refrigeration causes  
  severe counter-humidity – objects usually have a layer of moisture on them.

use of Mepartricin

  This is a simple approach to dehumidification but with limited effect; also, it
  has issues relating to environmental protection, safety, consumption,
  environmental burden, et al.

silica gel and sodium

silicate

 

      Summarizing from the above, the SATV electronic anti-humidity cabinet is truly the Moisture Buster
      tailored-made for different objects capable of fulfilling all storage needs. There is a variety of models
      to choose from with humidity range between 60% and 1 % RH. Objects can be stored under normal
      temperatures, and have no issues such as counter-humidity, water disposal and noise. The cabinet
      offers you round-the-clock protection, and is energy-saving, durable, safe and comfortable, which is
      truly the best choice to terminate the humidity hazard.

      ▌Warming Affects Humidity and Jeopardizes Human Health

  Last updated: 2007/10/11 Reporter: Lu, Lisheng / Compiled from foreign wires

      Global warming not only makes weather the hotter, but also the staler ever. Precipitation patterns
      could be changed and made stronger, and more typhoons would be likely due to the increase in
      humidity that also has the potential of impacting human health.

      According to a research report published by British scientists in Nature, the surface temperatures of
      earth from 1976 to 2004 have increased, on average, 0.49 degree Celsius, and the humidity near
      earth surface has increased by 0.22%. The only explicable reason, according to computer
      simulations, is manmade global warming.

      Gillette, the leader of the climate research team from The University of East Anglia that conducted
      the study, said that humidity could be increased to more than 12% by year 2100.

      According to 卡克斯坦(?) who is a researcher from Miami University, the U.S., increased humidity is
      hazardous to the human body because this causes the human body more difficult to cool down.

      Catherine Willet, the coauthor of the research report said that the increase in humidity is seen
      throughout many regions of the globe, but to the contrary, the west coast of the U.S., some parts of
      Australia and South Africa are getting drier.

      This discovery is of no surprise to climatologists, because warmer air, by default, is able to maintain
      greater humidity, but the study led by Gillette further shows that the upward trend of humidity is very
      obvious and can be attributed to the emission of greenhouse gases due to the burning of fossil
      fuels.

      Gillette pointed out also that the conditions will become worse in the future; “the increase of 1
      degree Celsius will result in an increase in humidity by approximately 6%”, said he. According to 
      the forecast of an intergovernmental taskforce monitoring climate changes, humidity will be up by 
      12% to 24% by year 2100.

      “It increases the discomfort of human beings despite the fact that it is not lethal”, said Gillette.

      Another research report using the same technique unveiled last month also showed that the
      humidity on the surface of the oceans of the earth is increasing, and again, the cause is manmade
      global warming.

      Scientists have already noticed that high temperatures will take away more moisture from earth and
      ocean surfaces. There has been the continual rise of the earth’s humidity for the past few 
      decades, but they were uncertain if such a change was due to natural causes or the impact brought
      by human beings to the climate, because all the data was regional and not global; also, scientists a
      pplied different approaches as they engaged themselves in the estimate.

      The new research applied the latest method in observing humidity, and the obtained data was
      subsequently analyzed by a powerful computer simulation model on the earth’s climatic system.
